MATRIX SETTING AND LINE CASTING MACHINE Filed Dec; 2e, 192a Patented Mar. 18, 1930 UNITED STATES PATENT OFFICE JULIUS DORNETH, OF KONBADSI-IOHE, NEAR TEGEL, GERMANY, ASSIGNOR TO THE FIRM 'IYPOGRAPH G. M. B. 11., 0F BERLIN, GERMANY MATRIX-SETTING AND LINE-CASTING MACHINE Application filed December 26, 1928, Serial No. 328,451, and in Germany August 9, 1928.

Continuous guiding wires cannot be used in matrix-setting and line-casting machines in which the matrices are conveyed in a closed path over guiding wires, because it is more convenient to use an elevator for raising the matrices after the casting operation is completed. This elevator moves upwards in a straight path from the casting location and thereafter transfers the matrices to the distributor Wires. The elevator is therefore the cause of discontinuity in the wires and thus involves difiiculties in mounting the free ends of the conveyor wires so that they are correctly spaced and always coincident with the wires carried on the elevator.

This invention relates to a means of mounting the guiding wires so that the ends thereof are immovably held in their correctly spaced position even after the machine has been in use for a long period of time.

A constructional example of the invention is illustrated in the accompanying drawings in which:

Figure 1 is a view of the point of discontinuity between the distributor wires and the wires leading from the setting location:

Figure 2 shows a detail, and

Figures 3 and 4 are an elevation and section respectively (on an enlarged scale) of the means whereby the conveyor wires are mounted in the elevator.

In machines in which the matrices a move in a continuous cycle, the latter are transferred from wires (1, leading from the setting location, to wires 7) of an elevator cl vertically guided in a frame 0 from which the said matrices are removed to be pushed on to the distributor wires 6. The wires a, e of the frame and those I) of the elevator (7 must be held so that they are always uniformly spaced without interfering with the guiding action of the lugs 0 of the matrices a. To this end, and according to the present invention, each wire end is allotted a folded sheetmetal holder 9 (Figure 2) the middle of which is bent to form an eye f the diameter of which accurately corresponds with that of the conveyor wire. The end of this holder is bent at right angles at h. The holder is secured to the frames 0 and cl by means of two screws '5 screwed into four-sided blocks 70 which are dimensioned so that they are in contact with the holders 03 throughout their length and fill the space between two holders.

These blocks therefore do not serve only the r purpose of securing means but also act as stifieners and holds the eye f correctly spaced at all-points.

The free ends of the conveyor wires a, 'b, e are provided in the known manner with pins as which are an accurate fit in the eyes 7 secured to both the lateral walls of the frame 0 and both the lateral walls of the elevator cl.

Having now particularly described and ascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim is 1. In a matrix-setting and line-casting machine a frame, wires guiding the matrices, pins on the ends of the wires, holders for the pins, each holder consisting of a folded sheet metal forming in the middle an eye for receiving the pin and a right-angle bent portion secured to the frame.

2. In a matrix-setting and line-casting machine a frame, wires guiding the matrices, pins on the ends of the wires, holders for the pins, each holder consisting of a folded sheet metal forming in the middle an eye for receiving the pin and a right-angle bent portion secured to the frame, a four-sided block bearing on the bent portion and accurately filling the space between two holders and means for fastening the bent portion and the block to the frame.

3. In a matrix-setting and line-casting machine a frame, Wires guiding the matrices, said wires comprising setting and distributing wires, an elevator bringing the line from the setting wires to the distributing Wires, said elevator comprising Wires, pins on the ends of all Wires, holders for the pins of the guiding Wires and of the Wires of the elevator, each holder consisting of a folded sheet metal forming in the middle an eye for receiving the pin and a right-angle bent portion, a four-sided block bearing on the bent portion and accurately filling the space between tWo holders and means for fastening the bent portion and the block.

In testimony whereof I afiix my signature.

JULIUS DORNETH.
